Phytochemical profiling, antioxidant and antibacterial efficacy of a native Himalayan Fern: (Makino) Nakai.

Present work elucidates the antioxidant and antibacterial activity of (Makino) Nakai along with chemical characterization using its aqueous (AEW), methanol (MEW), and hexane (HEW) extracts. Chemical profile of different extracts was illustrated by using Gas chromatography and mass spectrometry (GC-MS) analysis. Antioxidant activities were tested using DPPH and FRAP assays, total phenolic and flavonoid content by Folin-Ciocalteu and aluminum chloride method, respectively.

Seasonal Variation in Essential Oil Compositions and Antioxidant Properties of Acorus calamus L. Accessions.

(Sweet flag) is a known herbal drug commonly used in traditional medicine. Our aim was to perform seasonal and altitudinal phytochemical screening to assess the antioxidant activity of the essential oils in the rhizome and leaves of from three different altitudes. Phytochemical screening was performed using GC/MS analysis and in vitro antioxidant assay was done by different methods.
